MotoMummy has the best chain and sprocket deals out there, I got a driven steel sprocket set with an EK MVXZ chain for 178 shipped. If your bike is not listed, call them and they will email an invoice for your bike.
+1 Driven and Motomummy

Driven make a nice black steel rear that is lighter than stock, but not radically lightened so much as to compromise integrity (some lightened steel sprockets by other brands experienced failures). They are a little heavier than aluminum but will last longer.
